You want to copy the repository objects and the cross-client Customizing from the production system to create a non-production system.
Alternatively, you want to create a new non-production system for SAP NetWeaver BW with a repository identical to that of your production system.
System Shell Creation with SAP TDMS enables the creation of a new BW non-production system by copying the repository objects and cross-client objects from the production system and creating a system shell.
After the system shell creation, carry out the required data transfer using the available TDMS migration solutions to create a consistent non-production system.
